TAO, QUBIC, FLUX, DNX are all Useful Proof of Work (UPoW) or Proof of Useful Work (PoUW) digital currencies, will you please list all UPoW or PoUW digital currencies?
Useful Proof of Work (UPoW) or Proof of Useful Work (PoUW) is a consensus mechanism where computational power used in mining is directed toward solving real-world problems, unlike traditional Proof of Work (PoW), which often involves solving arbitrary puzzles. Based on available information, here are the digital currencies explicitly associated with UPoW or PoUW:
TAO (Bittensor): Utilizes a PoUW mechanism where computational resources are directed toward machine learning tasks, specifically training decentralized AI models. Miners contribute by performing useful computations for the Bittensor network, which aims to create a decentralized marketplace for AI.
QUBIC: Employs UPoW, where mining involves training artificial neural networks (ANNs) to solve complex problems. The computational effort contributes to both network consensus and real-world applications like machine learning, with rankings based on the effectiveness of AI miners.
FLUX: Operates a PoUW model within its decentralized computing ecosystem. Instead of wasteful computations, FLUX redirects mining power to practical tasks like supporting decentralized applications (dApps) and cloud infrastructure, compatible with blockchains like Ethereum and Solana.
DNX (Dynex): Uses a PoUW mechanism called Proof-of-Useful-Work (PoUW), where miners perform neuromorphic quantum computing tasks. These computations are designed to solve real-world problems, leveraging a decentralized network of quantum computing resources.
Additionally, one other project is noted in the context of PoUW:
Ofelimos: A blockchain protocol presented at the IACR Crypto 2022 conference, Ofelimos uses PoUW to achieve consensus while solving decentralized optimization problems. It employs the Doubly Parallel Local Search (DPLS) algorithm, with an example implementation using a variant of WalkSAT for Boolean problems. However, it’s unclear if Ofelimos is a standalone digital currency or a theoretical protocol.
Notes:
The list is limited to projects explicitly tied to UPoW or PoUW in the provided references and general knowledge. Other cryptocurrencies may use similar mechanisms but lack clear documentation as UPoW/PoUW.
The Internet Computer (ICP) is mentioned as using PoUW, where node machines perform useful smart contract computations instead of hashing. However, it’s not always classified as a currency in the same way as TAO or QUBIC, so it’s not included in the primary list.
No comprehensive list of all UPoW/PoUW currencies exists in the provided sources, and the concept is still emerging, so this list may not be exhaustive. Projects like TAO, QUBIC, FLUX, and DNX are the most prominent examples based on current data.
